Abstract: A photographic film that is especially useful as a motion picture print film is comprised of a support having, in order, on one side thereof an antihalation undercoat and at least one silver halide emulsion layer and having, in order, on the opposite side thereof an antistatic layer and a protective topcoat; wherein the protective topcoat is comprised of a polyurethane binder and a lubricant and the polyurethane binder has a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50000 lb/in.sup.2. The polyurethane binder provides a tough but flexible protective topcoat that is capable of resisting abrasion and scratching when the film is conveyed through a projector and capable of standing up to the repeated use to which motion picture print films are typically subjected.

Abstract: Disclosed herein are heat-activatable adhesive compositions comprising an amorphous condensation polymer which is characterized by having an acid component comprising a phthalic acid derivative and a glycol component comprising from about 15 to about 85 mole percent of (1) a linear aliphatic glycol having the structure HO--R--H wherein R is either: ##STR1## or --CH.sub.2 CH.sub.2 O--.sub.n wherein n is an integer from 2 to 4; and from about 85 to about 15 mole percent of (2) a branched aliphatic glycol having the structure: ##STR2## wherein R.sup.1 and R.sup.2 are alkyl. These polyester adhesives are further characterized as being soluble in halogenated solvents, having glass transition temperatures within the range of about -30.degree. to about 50.degree. C, and having high bonding strengths at elevated temperatures. They have been found useful in a variety of photographic materials, and particulary in photographic film units.
